• We will be examining the response times of several “official” Twitter accounts: CalFire, Butte County Sheriff, and Chico Fire Department.
• Why is this important?
  • Natural disaster require timely warnings and information. This makes it easier to overcome public misperception and helps different actors in responding to crises in a way that benefits the collective.
• How credible is this information?
• What about using television? Phone calls? Radio?
• That is why it is also very important to examine the times it takes for officials to issue official information and warnings to the public, such as evacuation notices, which can literally be life-saving information during disasters.

• Fewer people are using television and radio than ever before.
• Over reliance on phone calls or texts for emergency information (St. John, Paige, and Joseph Serna, 2018)
• Twitter has 64.2 million users, and a diverse user base.
• 77% of journalists say social media is important to them for learning about potential stories more quickly, and that it is important in reporting stories more quickly (Elliott 2018).
• During November of 2018 alone, CalFire’s official Twitter account gained about 35k followers, which shows them to be an important source of information for the public (SocialBlade, 2020).

• Disaster Response and Twitter
  • Why is Twitter data important during disasters?
    • Gives a “real-time view” of disasters, allows fast-flowing information quickly from official sources (Ford, 2018).
  • There is a need for unique updates across organizations given the volume of data produced because manually managing is not always practical right after a disaster (Ford, 2018).
• Potential Flaws in Phone-Based Warning Systems
  • “Butte County Sheriff’s office showed that the first evacuation orders requested by firefighters failed to connect. Half of the calls went to voicemail (St. John and Serna, 2018).”
  • This inefficiency presents a real problem within our system.
  • The police chief of Paradise said “there was no time for a citywide evacuation order — the city’s own system went down in the midst of a partial order” (St. John and Serna, 2018). With California having the most Twitter users, there needs to be a wide array of emergency notification methods through Twitter (Stirtz, 2020).

• Refiguration of disaster social relations
  • New communication technologies replacing traditional media, transformation of disaster visibility (Cottle 2014).
  • Individuals are central in emergency responses (Cottle 2014).
  • Civilian surge of information and worldwide engagement because of fast-flowing information, collaboration between citizens, disaster relief agencies, volunteers, and public figures (Cottle 2014).
• Limits to crisis data
  • When data collection starts, social media platforms can create analytical and ethical oversights (limited access to the internet during a disaster: power outages, etc) (Crawford and Finn 2015).
  • Traditional media was state-controlled, but that changed in more recent years (Crawford and Finn 2015).
  • Traditional media was state-controlled, but that changed in more recent years (Crawford and Finn 2015).
  • People cannot control how their data is used: privacy issue (Crawford and Finn 2015).

• How timely were public officials and emergency services twitter accounts in disseminating important and crucial information to the public during the Camp Fire?
  
• Most research done revolves around incidents such as earthquakes (only a sixth of cases pertained to wildfires).
  
• Our main goal is to examine the timeliness of social media in emergency management by examining the response times of specific accounts along the timeline of the Camp Fire.
  
• We will use a timeline to examine these response times more closely and compare them to the timeline of the actual disaster.

• 72,748 tweets were collected using the rtweet (Kearney MW 2019) package using R 3.6.2 (R Core Team) beginning the morning of November 11, 2018 by the Spring 2020 Advanced Data Science class at CSU, Chico. Tweets were collected Using the query: #CampFire, #campfire, #paradise, #Paradise or @CALFIRE_ButteCo"
  
• A timeline of events from the morning of November 8, 2018 was derived from the Chico Enterprise-Record. (Epley)
  
• We are observing tweets regarding seven public figures’ and organizations’ twitter accounts that were instrumental during the Camp Fire, specifically: @Cal_Fire, @CalFire_ButteCo, @ButteSherriff, @ChicoFD, @CountyOfButte, @Paradise_CA, and @ChicoPolice.
  • Data from these accounts are defined as “media” while all others are defined as “public”.

• Variable Creation: To successfully compare the response time of the local media accounts to the real life timing of events we populated a data frame with each event and time as specified by Chico Enterprise-Record’s timeline of the morning of the fire (Epley).
• Data Analysis: We analyzed the specific timing of emergency services and government entities’ tweets regarding pertinent information in relationship to the real life events through a timeline that incorporates both the twitter data and the derived timeline data in one merged timeline plot.
  • We additionally created a timeline documenting the comparison between times of general public tweets and tweets from our local media sources.

• We were most interested in initial response times data, so we filtered down the dataset to only include tweets that occurred during the first six hours from the fire starting.
• Each record in the data represents an individual tweet’s metadata. The variables from the metadata used throughout include:
  • Tweet content
  • User’s Twitter Handle
  • Whether the tweet was a retweet
  • Time the tweet was created
  • The events derived from Chico Enterprise-Record’s timeline (Epley)

While the original dataset includes 72,748 tweets, we are only concerned with the tweets that occur within the first 6 hours of the fire starting and those that directly address the fire. This ends up being just 446 tweets, which amounts to 0.61% of the overall data.

In the following timeline each dot signifies a tweet or event to show tweet times in comparison to the real event times. The majority of the tweets shown are evacuation warnings and orders.

After eliminating retweets for public tweets the following timeline compares the timing of tweets by the public vs the local media for the morning up until 10:00 AM.

• Our results show that Twitter can be used to disseminate important and potentially life saving information in a timely manner, as was seen on the timeline of events for the Camp Fire.
• From our Twitter data, we can also see that Twitter can provide individuals with this information in a consistent manner, when other media methods may be ineffective in sharing this data (such as losing power during a disaster and being unable to receive news via television).
• This ultimately means that social media platforms such as Twitter, if used properly, can be an important tool when it comes to emergency alert systems.

• When official accounts respond to events promptly, it gives the organization or person more credibility, especially in the context of natural disasters where people count on them to stay safe and informed on the changing situation.
• With a mounting number of people using Twitter, data collected from social media is useful in offering insight into public opinion.
• Retweets permeate information at a rapid pace, which enables a message to be communicated to a large number, of people, which can potentially limit disaster.
